BBA Black Beard Algae


I got it

I've increased lighting from 2 x 13 watt CFL's to 2 x 23 watt CFL's.

I have pressurized Co2, dose dry ferts, and 0.5ml of excel daily. What can/should I do to get rid of the BBA?

Thanks!

What's your CO2 looking like? I think an increase in light without an increase in CO2 helps the algae outcompete your plants for growth. But at this point since it's already there, do a search for "algae blackout" for a way to kill it off.

It's a 10g with 1BP0.6S Co2 is on from 10am-6pm and lights are on 11am-7pm. Drop checker is green.

I know i can get rid of the algae but what can I do so it doesn't come back?

Sufficient stable CO2 levels and remove decaying leaves as BBA typically grows on unhealthy leaves. At least in my case, this is my observation. BBA can come back if these CO2 levels drop too low and fluctuate

How do I stop them from fluctuating? Run Co2 24/7? The BBA is not super bad yet, but I want to stop it before it does get really bad.

No, dont run 24/7 if you dont need to. Just turn CO2 on before lights by like 30 mines to an hour. Add siesta as well. That will help buildup CO2.

The goal is to have the same concentration of CO2 in the water every day, while the lights are on, not to have it the same 24 hours a day. The green drop checker just means you are in the right ballpark for CO2 -you have 10-45 ppm, not 2-5 ppm - so you still need to adjust the bubble rate to get to the optimum bubble rate. You can do this by slightly increasing the bubble rate, then watch the fish for distress, and watch the plants to see if they grow better, more pearling, etc. Watch for a few days. If the plants do better, repeat this until either the fish are distressed, or the plants don't do any better, then back off to the last bubble rate. You need to have good oxygen concentration in the water for this to work well, so you need the water surface rippled all over, but no splashing. Using a wet/dry filter will give you the most dissolved oxygen.

I cured my BBA problem i had for months by the following steps....

1. "Borrow" 3 young SAEs from my LFS for a month to eat away at the stuff.
2. Regulate my pressurized CO2 output to an adequate level and stopped playing with it. I don't necessarily believe in the maximum output of CO2 theory. Im sure it works but too many tanks are successful without almost gassing the fish for it to be necessary.
3. Dosed Excel according to the bottle directions at water changes and daily. Did my dosing direct to varying affected areas for a while while filter was off for 10 minutes.
4. Lastly, and what I believe to be the most important, I switched to RO/DI water with a specific recipe of Equilibrium and Alkalinity Booster. I really believe BBA is the result of dirty, chemical and organic laden city water. Either by fueling the BBA or just hurting the plants growth rate. Switching to clean water made a huge difference in my tank.
